This has been implemented in Qt for quite some time. This patch adds the
same feature to AppKit. This is needed to run many WPT subtests with the
AppKit chrome. This is also needed to handle window.open, target=_blank
link clicks, etc.
This is overriding the URL passed to e.g. window.open and link clicks on
an <a target=_blank> element.
Note: This alone is not enough to support such use cases. We will also
need to actually implement opening child web views. But getting this fix
out of the way first makes that patch a bit simpler.
It's getting a bit unwieldy to maintain as an inlined string. Move it to
its own file so it can be edited with syntax highlighting and other IDE
features.
The main motivator here was noticing that --disable-sql-database did not
work with AppKit. Rather than re-implementing this there, move ownership
of these classes to WebView::Application, so that each UI does not need
to individually worry about it.
This is a preparation for upcoming changes where Gfx::Typeface will
depend on `FontDatabase::should_force_fontconfig()`, so we will no
longer be able to construct typefaces from FontDatabase constructor
because of circular dependency.
AppKit uses Private Use Area code points for a large collection of
functional keys (arrows, home/end, etc.). Re-assign them to 0 to avoid
tripping up WebContent's key handler.
Choosing options from the `<select>` will load and display that style
sheet's source text, with some checks to make sure that the text that
just loaded is the one we currently want.
The UI is a little goofy when scrolling, as it uses `position: sticky`
which we don't implement yet. But that's just more motivation to
implement it! :^)
On Android there's really no real way to provide command line flags.
We are using a dummy Main::Argument that only contains "ladybird"
as a name of the program.
The strings of Main::Argument cannot be empty, otherwise the program
throws an error. However the argc and argv can be set to 0 and nullptr
For some reason, IOSurface results in a completely blank render on Intel
machines. It's not clear why, so do not use IOSurface for now in order
to allow Intel users to run the browser.
Before this change, we were passing CGColorSpaceCreateDeviceRGB() to
CGImageCreate(), causing the system to assume that the image data is
in a device-specific RGB space without any color profile adjustments.
If your monitor is more vibrant than the assumed profile (for example,
a wide-gamut display), colors may appear over-saturated as there's no
correction applied for how the display actually renders those colors.
We now pass CGColorSpaceCreateWithName(kCGColorSpaceSRGB) instead,
which makes colors look the same in Ladybird as in other browsers. :^)
This allows us to get identical metrics on macOS and Linux. Without
this, Skia will use CoreText on macOS and give us slightly different
text metrics. That causes layout tests to be slightly different on
different platforms, which is a huge headache. So let's not do that.
You can now launch Ladybird and headless-browser with --force-fontconfig
to load fonts through fontconfig. Tests run in this mode by default.
The AppKit Application class is responsible for launching all helper
processes. This had to be moved to a .cpp file because we were unable to
include headers with the Protocol namespace in .mm files, as they would
conflict with the Protocol interface defined by Apple.
Now that this namespace has been renamed to Requests, we can remove this
workaround.
When working on the Inspector's HTML, it's often kind of tricky to debug
when an element is styled / positioned incorrectly. We don't have a way
to inspect the Inspector itself.
This adds a button to the Inspector to export its HTML/CSS/JS contents
to the downloads directory. This allows for more easily testing changes,
especially by opening the exported HTML in another browser's dev tools.
We will ultimately likely remove this button (or make it hidden) by the
time we are production-ready. But it's quite useful for now.
This forwards all drag-and-drop events from the UI to the WebContent
process. If the page accepts the events, the UI does not handle them.
Otherwise, we will open the dropped files as file:// URLs.

The identifier "Protocol" is claimed by Objective-C and Swift for use
by the language's built-in protocol conformance feature, which is
similar to Rust traits or Java interfaces.
Rename LibProtocol -> LibRequests, and its namespace from Protocol to
Requests to accomodate this.
We use instances of `Gfx::Bitmap` to move pixel data all the way from
raw image bytes up to the Skia renderer. A vital piece of information
for correct blending of bitmaps is the alpha type, i.e. are we dealing
with premultiplied or unpremultiplied color values?
Premultiplied means that the RGB colors have been multiplied with the
associated alpha value, i.e. RGB(255, 255, 255) with an alpha of 2% is
stored as RGBA(5, 5, 5, 2%).
Unpremultiplied means that the original RGB colors are stored,
regardless of the alpha value. I.e. RGB(255, 255, 255) with an alpha of
2% is stored as RGBA(255, 255, 255, 2%).
It is important to know how the color data is stored in a
`Gfx::Bitmap`, because correct blending depends on knowing the alpha
type: premultiplied blending uses `S + (1 - A) * D`, while
unpremultiplied blending uses `A * S + (1 - A) * D`.
This adds the alpha type information to `Gfx::Bitmap` across the board.
It isn't used anywhere yet.
